As shown in FIGS. 13 and 17, the two or more gaskets 420 extend from theengagement surface 396 and are configured to be received by theintermediate necked portion 22 of the cooking vessel 14. It should beunderstood, that the number, shape and configuration of the one or moregaskets 420 can vary. By way of explanation, and not limitation, asingle gasket 420 may be disposed on the engagement surface 396 wherethe gasket 420 defines a linear protrusion disposed along the engagementsurface 396. In such an embodiment, the cross-sectional shape of thelinear protrusion can include, but not be limited to, arcuate orrectilinear cross sections. In other alternate embodiments, the linearprotrusion can include an extruded cavity within the length of thelinear protrusion, wherein the coupling of the engagement surface 396 tothe intermediate necked portion 22 of the cooking vessel 14 can compressthe linear protrusion and define a seal between the first well 24 andthe second well 26. Alternatively, the gasket 420 may take on anon-linear configuration.

Referring back to the illustrated embodiment, as shown in FIGS. 11-18,the arcuate dividing wall 32 is made of a substantially rigid materialincluding, but not limited to, metals, plastics, rubberized materials,glass or ceramic material or other substantially rigid material. Thematerial selected for the arcuate dividing wall 32 should also be of amaterial that can substantially withstand deformation when exposed toheat levels experienced in kitchen cooking appliances.

As illustrated in FIGS. 13 and 17, the illustrated gasket 420 is made ofa substantially flexible material such as a rubberized material orplastic material that can create the desired seal between the first andsecond wells 24, 26 when the arcuate dividing wall 32 is engaged withthe intermediate necked portion 22 of the cooking vessel 14. Inaddition, in certain embodiments, it is contemplated that the one ormore gaskets 420 may be selectively removable from the engagementsurface 396 of the arcuate dividing wall 32. In this embodiment, theengagement surface 396 can include a gasket receptacle portion 422 forreceiving the one or more gaskets 420.

Alternatively, in other embodiments, the one or more gaskets 420 may beformed with and be an integral part of the arcuate dividing wall 32. Insuch an embodiment, it is preferred that the arcuate dividing wall 32 bemade of a plastic or rubberized material so that the one or more gaskets420 can create the desired selective seal between the arcuate dividingwall 32 and the cooking vessel 14.

Referring again to the illustrated embodiment, as shown in FIGS. 11,13-15 and 18, the arcuate dividing wall 32 can also include a handleportion 424 disposed proximate an upper portion 426 of the arcuatedividing wall 32. The handle portion 424 can define an opening proximatean upper portion of the arcuate dividing wall 32. In alternateembodiments, the handle portion 424 can include a gripping ridgedisposed proximate the upper portion 426 of the arcuate dividing wall32. In other embodiments, the handle portion 424 can be a separate piececoupled proximate the upper portion 426 of the arcuate dividing wall 32.

As shown in the illustrated embodiment of FIGS. 8A, 13, 16 and 17, aconvex surface 428 of the arcuate dividing wall 32 is configured to besubstantially vertical, while the concave surface 388 is substantiallyslanted to match the frusto-conical curvature of the first and secondwells 24, 26. The substantially vertical orientation of the convexsurface 428 and the substantially slanted configuration of the concavesurface 388 defines a tapered vertical cross-section of the arcuatedividing wall 32 having a narrow upper portion 426 and a widened bottomedge 394 that at least partially defines the engagement surface 396.

In an alternate embodiment, the first and second sides 406, 408 of theintermediate necked portion 22 can include an engagement mechanism forreceiving the one more gaskets 420 of the arcuate dividing wall 32. Inthis embodiment, the engagement mechanism can include an engagementchannel configured to receive the one or more gaskets 420 of the arcuatedividing wall 32, where the engagement channel can at least partiallyinclude the first and second notches 402, 404.

Alternatively, the engagement mechanism can include an engagementprotuberance that extends from the first and second sides 406, 408 ofthe intermediate necked portion 22 where the engagement protuberance isconfigured to be received by the one more gaskets 420 of the arcuatedividing wall 32. In these alternate embodiments, the engagement channeland the engagement protuberance cooperatively engage at least a portionof the one or more gaskets 420 of the arcuate dividing wall 32. In thismanner, the engagement mechanism slidably receives the arcuate dividingwall 32 and the one or more gaskets 420 of the arcuate dividing wall 32.

In the various embodiments that include the engagement channel, thecooking vessel 14 can include first and second filler members that canbe slidably engaged into the engagement channels when the arcuatedividing wall 32 is selectively removed from the cooking vessel 14 tosubstantially prevent the contents of the cooking vessel 14 fromentering the engagement channel.

Referring again to the illustrated embodiment, as shown in FIGS. 13 and17, the first and second side edges 390, 392 of the arcuate dividingwall 32 are contoured thereby defining an engagement channel 430 thatsubstantially matches the curvature of the first and second sides 406,408 of the intermediate necked portion 22 of the cooking vessel 14defining an engagement protuberance 432. In this manner, the engagementchannel 420 of the arcuate dividing wall 32 slidably engages theengagement protuberance 432 of the intermediate necked portion 22 anddefines a lateral interference connection between the first and secondside edges 390, 392 of the arcuate dividing wall 32 and the first andsecond sides 406, 408 of the intermediate necked portion 22. Thislateral interference connection substantially limits the lateralmovement of the arcuate dividing wall 32 within the intermediate neckedportion 22, while allowing the desired operable vertical movement of thearcuate dividing wall 32 within the intermediate necked portion 22.

As best illustrated in FIG. 12, the concave surface 388 of the arcuatedividing wall 32 and the second well 26 define a circular cooking zone440 that is configured to define the second mixing zone 372. The convexsurface 428 of the arcuate dividing wall 32 and the first well 24 definea crescent cooking zone 442, where the mixing functions of the cookingappliance kit 10 are substantially inoperable. As discussed above, thearcuate dividing wall 32 can be reversed such that the circular cookingzone 440 is at least partially defined by the first rounded end 18 andthe crescent cooking zone 442 is at least partially defined by thesecond rounded end 20.

Also, as best illustrated in FIGS. 8-11, the flared rim flange 348 ofthe cooking vessel 14 includes first and second drive arm receptacles450, 452. As will be more fully described below, the first and seconddrive arm receptacles 450, 452 are configured to receive the first andsecond drive arms 34, 36. The first and second drive arm receptacles450, 452 are further configured to selectively orient the first drivearm 34 over the first well 24 and the second drive arm 36 over thesecond well 26. In alternate embodiments, the drive arms can be switchedsuch that the first and second drive arm receptacles 450, 452 orient thefirst drive arm 34 over the second well 26 and the second drive arm 36over the first well 24.

Additionally, as shown in FIGS. 8-11, the first and second drive armreceptacles 450, 452 are substantially rectangular to match theillustrated first and second drive arms 34, 36. In alternateembodiments, the drive arm receptacles 450, 452 and the drive arms canbe rounded or have a different polygonal cross-sectional shape. Thefirst and second drive arm receptacles 450, 452 and the first and seconddrive arms 34, 36 cooperate to define a substantially close fit tosubstantially prevent the contents of the cooking vessel 14 fromescaping the cooking vessel 14 during use.

In other alternate embodiments, the drive arm receptacles 450, 452 caninclude receptacle gaskets that provide a seal between the first andsecond drive arms 34, 36 and the first and second drive arm receptacles450, 452, respectively. Such a seal can further prevent liquids andother contents from escaping the cooking vessel 14 during cooking ormixing operations, or both.

Referring again to the illustrated embodiment, as best illustrated inFIGS. 10 and 19-22, the cooking appliance kit 10 includes a drive system40 where the first and second drive arms 34, 36 are configured to beremovably engaged and in operable communication with the drive system40. The drive arms 34, 36 may be laterally pivotable relative to thecooking appliance kit 10. It is also contemplated that the drive arms34, 36 could be independently upwardly pivotable. Further, the drivearms 34, 36 could be pivotable with the lid 46, such that when a userlifts the lid 46, the drive arms 34, 36 are also lifted. As shown inFIG. 19, the drive system 40 includes an electric motor 78 coupled withand in operable communication with a drive wheel 470. First and secondidler wheels 472, 474 are disposed proximate the drive wheel 470. Aplurality of wheel plates 476 are configured to secure the electricmotor 78 and the idler wheels 472, 474 to the bottom panel 70 of thehousing 12 within the secondary cavity 190. The wheel plates 476 areconfigured to secure the idler wheels 472, 474 and the drive wheel 470to the bottom panel 70 and also allow for the rotational movement of theidler wheels 472, 474 and the drive wheel 470.

As shown in FIG. 19, a drive belt 478 is configured to engage the drivewheel 470 and the first and second idler wheels 472, 474, and define anoperable communication between the drive wheel 470 and the first andsecond idler wheels 472, 474. First and second drive shafts 480, 482extend from proximate ends 484 at the first and second idler wheels 472,474 and are disposed co-linear with first and second rotational driveaxes 486, 488 of the first and second idler wheels 472, 474,respectively, to distal ends 490 of the drive shafts 480, 482 proximatethe first and second drive shaft openings 292, 294 of the top flange 38of the heating cavity wall 192.

FIG. 19 also shows first and second drive receptacles 492, 494 that arecoupled to distal ends 490 of the first and second drive shafts 480, 482wherein the first and second drive receptacles 492, 494 extend throughthe first and second drive shaft openings 292, 294 (shown in FIG. 10)and are further configured to rotate within the first and second driveshaft openings 292, 294. First and second grommets 496, 498 are coupledto the first and second drive shaft openings 292, 294, respectively, andsecure the first and second drive receptacles 492, 494 within the firstand second drive shaft openings 292, 294 while allowing the rotationalmovement of the first and second drive receptacles 492, 494 within thefirst and second grommets 496, 498.

As further illustrated in FIG. 19, to allow for the desired rotationalmovement of the first and second drive receptacles 492, 494 within thefirst and second grommets 496, 498, the first and second drivereceptacles 492, 494 can be coupled to an inner-facing surface 500 ofthe first and second grommets 496, 498 by a rotational sliding assemblythat can include, without limitation, ball bearings, cylindricalbearings, lubricated members, or other rotationally slidable interface.

Also, as illustrated in FIGS. 19 and 22, the first and second drive arms34, 36 each include an engagement gear 502 disposed at engagement ends504 of the first and second drive arms 34, 36 that are configured to beselectively received by at least one of the first and second drivereceptacles 492, 494. In this manner, each engagement gear 502 is inoperable communication with at least one of the drive shafts 482, 484and at least one of the idler wheels 472, 474, and the drive wheel 470of the electric motor 78. Each drive arm 34, 36 contains a drive train506 having a first train end 508 including the engagement gear 502 and asecond train end 510 including a tool impeller 518 disposed atrotational ends 514 of the first and second drive arms 34, 36. A drivearm enclosure 516 is configured to receive the drive train 506 andsecure the drive train 506 within the drive arm enclosure 516 bylimiting the vertical and lateral movement of the drive train 506 withinthe drive arm enclosure 516 and also allowing the rotational movement ofthe drive train 506 such that the engagement gear 502 of the drive train506 is in operable communication with the tool impeller 518 of the drivetrain 506.

As shown in FIGS. 19-22, each drive arm includes the first and secondarm connectors 300, 302 disposed on the engagement end 504 of the firstand second drive arms 34, 36. Each of the first and second armconnectors 300, 302 can include a tubular channel 530 extendingvertically through the drive arm enclosure 516 proximate the engagementend 504 of the drive arms 34, 36 and a connecting assembly 532 having aconnector end 534 extending upward through the tubular channel 530 to aknob end 536 for turning the connector end 534. The connector end 534 isconfigured to be received by the first and second drive arm interfaces296, 298 in the top flange 38 of the heating cavity wall 192. Asdiscussed above, the drive arms 34, 36 are configured to engage thedrive system 40 and the top flange 38 of the heating cavity wall 192,such that the rotational ends 514 of the first and second drive arms 34,36 are disposed over central axes of the first and second wells 24, 26thereby defining the at least partially intersecting first and secondmixing zones 370, 372 within the first and second wells 24, 26,respectively (shown in FIGS. 8 and 9).

As illustrated in FIGS. 19 and 20, first and second tool receptacles542, 544 are disposed within the tool impellers 518 of the first andsecond drive arms 34, 36, respectively. The each tool impeller 518 ofthe first and second drive arms, 34, 36 defines first and secondrotational mixing axes 546, 548 that are selectively and substantiallyintersect the first and second well centers 356, 358.

In alternate embodiments, the drive system 40 can include a drive gearcoupled to the electrical motor and first and second idler gears coupledwith and operably engaged with the drive gear where the first and seconddrive shafts 480, 482 are coupled with the idler gears and where thedrive shafts 480, 482 define first and second rotational axes of theidler gears. This embodiment can operate without a drive belt 478 andcan substantially prevent slippage between the drive belt 478 and thefirst and second idler gears and the drive gear.

Referring again to the illustrated embodiment of FIGS. 2 and 3, when thedrive arms 34, 36 are selectively engaged with the housing 12 in thefirst and second drive interfaces 296, 298, the drive arms 34, 36 arereceived by the first and second drive arm receptacles 450, 452 of theflared rim flange 348 of the cooking vessel 14. In this manner, thefirst and second lid members 326, 328 are configured to define closedpositions wherein the perimeters of the first and second lid members326, 328 engage the flared rim flange 348 of the cooking vessel 14,without the first and second lid members 326, 328 interfering with theextension of the first and second drive arms 34, 36 over the first andsecond wells 24, 26, respectively.

As discussed above, and as further shown in FIG. 8, the selectiveengagement of the arcuate dividing wall 32 within the intermediatenecked portion 22 defines a non-mixing area within the crescent cookingzone 442. In this configuration, the first or second drive arm 34, 36that extends over the crescent cooking zone 442 can be selectivelyremoved without interfering with the selectively engaged first or seconddrive arm 34, 36 coupled to the drive system 40 and that extends overthe circular cooking zone 440 and defining one of the first and secondmixing zones 370, 372 within the circular cooking zone 440.

It is contemplated that drive arm spacers can be inserted into at leastone of the first and second drive arm receptacles 450, 452 when eitherthe first drive arm 34, the second drive arm 36, or both are disengagedfrom the housing 12. The drive arm spacers can be configured to have across-sectional shape similar to that of the first and second drive armreceptacles 450, 452. In this manner, the drive arm spacers canselectively and substantially occupy the first and second drive armreceptacles 450, 452 to substantially prevent contents of the cookingvessel 14 from being expelled from the cooking vessel 14 through thefirst or second drive arm receptacles 450, 452 during use of the cookingappliance kit 10.

Referring back to the illustrated embodiments as shown in FIGS. 8-9 and19-22, the stirring and flipping wands 42, 44 are configured forselective engagement within at least one of the first and second toolreceptacles 542, 544. The selective engagement of the stirring andflipping wands 42, 44 further defines the first and second mixing zones370, 372 (shown in FIG. 9). The selective engagement of the first andsecond drive arms 34, 36 to the drive system 40 further defines a mixingpattern of the first and second mixing zones 370, 372 wherein the firstand second mixing zones 370, 372 at least partially intersect. The drivesystem 40 and the drive arms 34, 36 are further configured such that therotation of the stirring or flipping wand 42, 44 connected to the firstdrive arm 34 does not interfere with the rotational movement of thestirring or flipping wand 42, 44 selectively coupled with the seconddrive arm 36 as the stirring and flipping wands 42, 44 rotate throughthe intermediate necked portion 22. In this manner, the first and secondmixing zones 370, 372 are allowed to intersect without the stirring andflipping wands 42, 44 colliding during operation of a mixing function atthe cooking appliance kits 10.

As illustrated in FIG. 19, the drive belt 478 couples to the drive wheel470 and first and second idler wheels 472, 474 creates a commondirectional rotation of the first and second idler wheels 472, 474thereby creating a common directional of rotation for the remainder ofthe drive system 40 and the drive arms 34, 36. In this manner, thestirring and flipping wands 42, 44 can be configured to rotate in thesame direction (i.e. clockwise or counterclockwise).

In alternate embodiments, the drive system 40 and the drive arms 34, 36can be configured to have opposite directional rotations such that oneof the stirring or flipping wands 42, 44 will rotate clockwise and theother stirring or flipping wand 42, 44 will rotate counterclockwise. Byway of explanation and not limitation, this opposite rotation can beaccomplished by two drive belts where one drive belt couples the drivegear 470 to the first idler wheel 472 and the second drive belt couplesthe first idler wheel 472 to the second idler wheel 474. Alternatively,the configuration of the connection between the drive train 506 and theengagement gear 502 can create the opposite directional rotation of thefirst and second drive arms 34, 36.

In an alternate embodiment as shown in FIGS. 23 and 24, the drive system40 is disposed within the lid assembly 324 such that when the lid 46 isin the closed position, the drive system 40 is disposed over the cookingvessel volume 350. A service channel 560 is disposed within the lid 46and extends from the drive system 40 to the lid hinge 322 and into thehousing 12, such that the drive system 40 can be coupled with thecontrols 122 to create a fluid communication between the drive system 40and the controls 122 while still containing equipment and wiring withinthe service channel 560. A drive gear 562 and idler gears 564 aredisposed on the underside 566 of the lid 46 in an operable communicationwith the motor 78. In this alternate configuration, no drive arms arepresent and the tool impellers 518 and tool receptacles 542, 544 aredisposed at centers of the idler gears 564.

In addition, as shown in FIGS. 23 and 24, when the lid 46 is in theclosed position, the idler gears 564 are disposed above the first andsecond wells 24, 26, respectively. The selective engagement of thestirring and flipping wands 42, 44 within the first and second toolreceptacles 542, 544 defines the first and second mixing zones 370, 372within the cooking vessel 14, wherein the first and second mixing zones370, 372 at least partially intersect. The lid 46 and the servicechannel 560 cooperate to provide rotational movement of the lid 46without interfering with the equipment and wiring disposed in theservice channel 560.

Referring now to FIGS. 25-47 of the illustrated embodiment, anotheraspect of the cooking appliance kit 10, includes a mixing tool setincluding a pair of stirring wands 42, a pair of flipping wands 44, anda pair of combination wands 590 having stirring and flipping surfaces.Each of the stirring, flipping and combination wands 42, 44, 590 isconfigured for selective engagement in either of the first and secondtool receptacles 542, 544 (FIGS. 19-20).

The first pitch angle 612 is greater than the second pitchangle 614. As illustrated, the first and second pitch angles 612, 614are 60 degrees and 25 degrees, respectively. However, alternateconfigurations of the first and second pitch angles 612, 614 can beimplemented, where the second pitch angle 614 is greater than or equalto the first pitch angle 612, without departing or interfering with thespirit of the illustrated embodiments.

Additionally, as illustrated in FIGS. 25-31, a second tapered stirringsurface 618 is defined by the substantially horizontal stirring member604. The second tapered stirring surface 618 includes a third pitchangle 620 proximate the lower end 616 of the substantially verticalstirring portion 602 defining a wand base 622 of the substantiallyhorizontal stirring member 604, and a fourth pitch angle 624 proximate awand tip 626 of the substantially horizontal stirring member 604. Asillustrated, the third and fourth pitch angles 620, 624 are 28.7 degreesand 13.75 degrees, respectively. The third pitch angle 620 is greaterthan the fourth pitch angle 624. However, as discussed above, theconfiguration of the third and fourth pitch angles 620, 624 can varysuch that the fourth pitch angle 624 is greater than or equal to thethird pitch angle 620.

Also, as illustrated in FIGS. 8-9 and 25-31, the selective operableengagement of the stirring wands 42 within the first and second toolreceptacles 542, 544 define the first and second mixing zones 370, 372that at least partially intersect at the intermediate necked portion 22(shown in FIG. 9).

In an alternate embodiment of the stirring wand 42, the coupling arm 592includes a vertical support member that extends along the rotationalaxis of the tool impeller 518 and connects with the tip of thesubstantially horizontal stirring member. In this embodiment, the firstend 596 of the coupling arm 592 engages at least one of the first andsecond tool receptacles 542, 544 in a substantially horizontalorientation. A curved realignment member extends from the first end 596of the coupling arm 592 and is configured to realign at least a portionof the coupling arm 592 and the vertical supporting member of thecoupling arm 592 within the rotational axis of the tool impeller 518(similar to as shown in FIGS. 32-39).

Referring again to the illustrated embodiments as best shown in FIGS.32-39, the flipping wand 44 includes a vertical support member 630 withan upper portion 656 that defines the coupling arm 592 and a lowerportion 658 that extends to a substantially horizontal flipping portion632 that includes a bottom surface 634 that slidably rotates over thecooking vessel base 352 (shown in FIG. 12) and a top surface 636 thatincludes a proximal portion 638, an intermediate portion 640 and adistal portion 642 where the height of the intermediate portion 640 isless than the height of the proximal portion 638 and the distal portion642. The height of the distal portion 642 is greater than the height ofthe proximal portion 638. The coupling arm 592 is disposed at the upperportion 656 of the vertical support member 630. The second end 600 ofthe coupling arm 592 couples to a curved realignment member 644 thatconnects the coupling arm 592 to the lower portion 658 of the verticalsupport member 630, and orients the lower portion 658 of the verticalsupport member 630 within the rotational axis of the tool impeller 518(FIGS. 19 and 20). The lower portion 658 couples to the substantiallyhorizontal flipping portion 632 proximate the distal portion 642.

As illustrated in FIGS. 32-39, the substantially horizontal flippingportion 632 of the flipping wand 44 defines a substantially arcuateleading edge 646 disposed proximate the bottom surface 634. A taperedflipping surface 648 is defined by the substantially horizontal flippingportion 632 where the tapered flipping surface 648 extends from thebottom surface 634 to the top surface 636. The tapered flipping surface648 includes a first flipping angle 650 proximate the proximal portion638, a second flipping angle 652 proximate the distal portion 642, and athird flipping angle 654 proximate the intermediate portion 640. Thethird flipping angle 654 is less than the first and second flippingangles 650, 652 and the second flipping angle 652 is less than the firstflipping angle 650. As illustrated, the first, second, and thirdflipping angles, 650, 652, 654 are 62.8 degrees, 49.8 degrees, and 38.8degrees, respectively. In addition, the selective engagement of theflipping wands 44 within the first and second tool receptacles 542, 544defines the first and second mixing zones 370, 372 within the first andsecond wells 24, 26 wherein the first and second mixing zones 370, 372at least partially intersect within the intermediate necked portion 22(shown in FIG. 9).
